所以我制作了一个程序,要求用户输入一个值。我想通过消息小部件(或标签小部件)显示值,并在输入新输入时更新。
def Enter():
s = v.get()
print (v.get())
e.delete(0, END)
e.insert(0, "")
#Code, Code, Code
...
# Area To Enter Text
v = StringVar()
e = Entry(root, textvariable=v)
e.pack()
m = Message(root, text = "Your Input")
m.pack()
# Enter Button
b = Button(root, text="OK", command=Enter)
b.pack()
是否有办法让v的变量替换Message Widget的文本?
注意:
如果我用text
替换textvariable
,它会在按下每个字符键后更新文本,我需要在用户按下按钮时更新文本。
我的完整代码:
from tkinter import *
import os
# All Functions Below
def callback():
print ("HI")
def Exit():
os._exit(0)
def Enter():
s = e.get()
print (e.get())
m.configure(text=s)
e.delete(0, END)
e.insert(0, "")
def Population():
root = Tk
root.mainloop()
def SurvivalRate():
root = Tk
root.mainloop()
def BirthRate():
root = Tk
root.mainloop()
def NewGen():
root = Tk
root.mainloop()
root = Tk()
generation = 0
menubar = Menu(root)
menubar.add_command(label="Hello!", command=callback)
menubar.add_command(label="Quit!", command=Exit)
# Area To Enter Text
e = Entry(root)
e.pack()
m = Message(root, text = e)
m.pack()
# Enter Button
b = Button(root, text="OK", command=Enter)
b.pack()
Pop = Button(root, text="Population", command=Population)
Pop.pack()
答案 0 :(得分:4)
只需添加:
m.configure(text=s)
到你的职能部门:
def Enter():
s = v.get()
print (v.get())
m.configure(text=s)
e.delete(0, END)
e.insert(0, "")
作为旁注,您不一定需要StringVar()
。下面的代码将完全相同:
def Enter():
s = e.get()
m.configure(text=s)
e.delete(0, END)
e.insert(0, "")
#Code, Code, Code
...
# Area To Enter Text
e = Entry(root)
e.pack()
m = Message(root, text = "Your Input")
m.pack()
# Enter Button
b = Button(root, text="OK", command=Enter)
b.pack()
root.mainloop()
